obtained are consistent with those obtained by the anti-inflammatory screening where compounds 25 and 29 proved to be the most active ones among the other compounds with %GI ranging from 31.5 to 62.5% and they exhibited the lowest IC50 values as well. The ADMET analysis of the tested compounds was also performed in addition to the molecularmodelingstudies that included flexible alignment, surface and
合成了一系列新的苯并咪唑并噻唑衍生物。通过诸如IR,NMR和质谱的光谱技术确认了产物的结构。通过体外COX酶抑制试验或通过角叉菜胶爪水肿技术在体内评价被测化合物的抗炎活性。结果显示,化合物25和29代表整个系列中活性最高的化合物,对COX-1的抑制率分别为72.19、72.07和对COX-2的抑制率分别为87.46、87.38。有趣的是,所有合成化合物的IC50值均低于参考药物塞来昔布和萘普生,表明它们的效价更高。对于化合物25,它显示出比塞来昔布和萘普生分别强效约340和198倍的COX-1抑制剂(IC50值为0.044对15.000和8。700 µM),效力是与COX-2抑制剂相同的药物的10倍和115倍(IC50值是4.52 vs. 40.00和520.00 nM)。还评估了产品的抗肿瘤活性,获得的结果与通过抗炎筛选获得的结果一致,在该化合物中,化合物25和29被证明是活性最高的化合物,%GI在31
